Localization of a single-point magnetic target in the special geomagnetic field

This paper presents a set of linear equations for the localization of a single magnetic target in the special background of smooth geomagnetic field and geomagnetic anomalies, which serves as a solution to the problem of the localization of a single magnetic object for small area. Meanwhile computer simulation and error analysis are also provided. The results indicate that this mathematical model is relatively satisfying for medium/short-range localization in special geomagnetic background and has some reference value in practical application to some extent.
